there are 3 different types among addiction, condensation, transparent and translucent.Which one would it be the best for buttons? please hlep me to choose.

It costs 300 DKK plus taxes (25%) per kilo (50 euros/kilo) plus shipping if i can t go and pick it up myself.I would share a kilo with anybody interested

hi there

you touch a delicate point indeed, i have no moulding box so far.My idea is to take a "print" (how would you say that?) of a micro kontrol pad with fimo, and then use silicone to get a button.wish me good luck ... but if you can find anything with the proper shape "in negative", there you go.

interesting topic...

i did some experiments with silicone and i think to make a "negative" is pretty simple. I thought about making my "rubber buttons" out of a piece of wood. (as positive shape) - in the second step i will do a negative form with gypsum (gips - CaSO4).

Normally, the silicone is used to make a negative whitch is filled with gypsum later....

i was talking to some plastic manufacturers what is the ideal material for my idea and they also said me i need to get a plastic and not silicone.. and the price for this material was also about 50 € per kilogramm...

my project is now stopped for 3 weeks - because of holidays ;)

cheers

you get the rubber feeling also with some plastic materials ... the material i was talking about was some kind of PUR (polyurethane) and it is also a type of rubber... i have the data sheets here (only in german) ... i'm a learned chemist ;)

i have to talk to my teachers at school ... maybe they can give me some inspiration ... :/
